This invention relates to gas making apparatus, and has for an object to provide meansfor removing deposits from pipes or conduits employed in carrying gas from retorts, and the device may be regarded as an improvement in means for establishing communica- 7 tion between retorts, the gas washer standpipe and the waste heat flues.

It is an object of this invention to utilize heat from the retorts, for burning out the retorts and the connection between the retorts and the washer stand-pipe after the gas has been discharged from the retort and while the retort is being recharged; and it is a further object of this invention to provide novel means by which the operators or stokers may interrupt direct communication between the retort and the washer stand-pipe and divert heat which radiates from the retort while it is being drawn and rechar ed to the connections between the retort am? the washer standpipe so that the same may be clearedv of deposits which, under ordinary conditions, accumulate in the connections and impede the -flow of gas from the retort to the washer stand-pipe, the deposits accumulating in the retorts and connections being discharged into the waste heat flues which are usually adjacent to the washer stand-pipes.

With the foregoing and other objects in view, theiinvention consists in the means for removing deposits from washer stand-pipes and their connections, as hereinafter more fully setforth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like charactersdenote corresponding parts in the several views, and in which- Figure 1 illustrates a view in elevation of a fragment of a gas producing apparatus with the invention applied thereto;

Figure 5 is a side elevation, partly in section, showing the stand-pipe, the waste heat. flue, the retort partly in section and associated parts.

The invention forming novel subjectmatter of this application is a gas producing apparatus having retorts of usual construction, such retorts extending through the front walls of a furnace, each retort having a mouth piece and a door, both located beyond the front wall of the furnace.

The mouth pieces of each of the retorts are in direct communication with a casing that leads to flues of a chimney, one flue constituting a stand or washer pipe and the other flue a waste heat flue, the casing having associated therewith a damper for establishing communication with either of the flues', the casing being constructed to provide direct communication of the retort with the standpipeor flue and also communication with a waste heat flue, especially when the door of the retort is opened. Such construction provides means whereby when the stand-pipe or flue has its opening in communication with the casing closed, at which time the door of' the retort may be opened, there will be induced an up-draft in the waste heat flue that carries with it light ash, gas and other light residue which may be drawn b the up-draft into the waste heat flue, thereby preventing such material and heated air bein projected of the furnace.

In practice, each vertical bank of retorts is provided with a washer stand-pipe and wit a waste heat flue, and a casing between and the mouth pieces tional forms of seal boxes with which the of the retorts, the casing being of such .con-

said valve and its operating partsare not subjected to the intense heat produced within the retort.

In these drawings, 5 and 6 denote convenwasher stand-pipes 7 communicate and the washer stand-pipes are provided with the usual connections for a water line 9. The washer stand-pipes or fines have the usual ports or openings such as 10 which communicate with retorts 11 through the mouth pieces 12 and extensions 14 which communicate with a casing or valve box 13.

In the present embodiment of thejinvention, a valve box 13 is provided at each port of the washer stand-pipe.

Waste heat flues 15 are parallelwith the washer stand-pipes 7 and communicate with the valve boxes or casings 13 with the several ports 10 and 16 with the flue of the washer stand-pipe 7, and the waste flue 15: of the chimney, the flues being contiguous 1n order that the valve box may be of a minimum size. Each waste heat flue 15 in horizontal almement with the orts or openings 10 has ports the valve slidably seated, retaining strips 18.

such as 16, eac of which corresponds with one of the ports 10, and a valve box 13 applied to the washer stand-pipe and to the heat flue, the valve box communicating with the washer stand-pipe and heat flue, according to the position of a controlling valve 17 i which is mounted to reciprocate in the valve box 13 with relation to the ports 10 and 16 in order that they may be opened or closed at the will of an operator. Any suitable oint or slidewaymay be provided between the valve and the valve box to insure proper sealing of the orts, but those are details of construction w ich may be changed to suitparticular requirements. .7

As one embodiment of a means for holding may be secured in any appropriate wa to the inner wall of the valve box, and the vilve may have flanges or reduced ed es 19 which are slidable between the sur aces of the washer stand-pipe and heat flue being re-' tained in such relation by the stu s 18. Of course an' airtight joint will pre erably be formed between the valve box 13 and the pipe 14 which connects the valve box with a retort.

As a means for manipulating the valve in the box, each valve box may have a rod 20 which is connected to the valve and which has its outer end connected to a lever 21 pivoted on an arm 22 which lever may be manipulated to move the valve so that it will close a port 10 or a port 16. It will be desirable also to provide the valve box with an opening of suitable type, through which the link or red 20 is passed and will move to provide means for rendering the opening leakproof between the valve box and the said rod. It will be apparent from an inspection of the drawing and from the foregoing descrip tion that any de osits which accumulate in the connections etween the washer standpipe and the mouth pieces 13 and 14 while the retort is being used for the manufacture or production of gas can be subjected to the radiating heat from the retort while the retort is'being recharged. When an operator sets the valves to establish communication between the stand-pipe and the retort, communication between the retort and the heat flue will be interrupted, whereas when the valve is set to interrupt communication between the stand-pipe and the retort, hot gas from the-retort will pass to the waste heat flue through the valve boxes, so that the said valve boxes and their communications will be used for the purpose of removing deposits which would tend to foul the stand-pipe and the retorts. By reason of the provision of the alternate connections between the retort, the

stand-pipe and the heat flue, the connections will be utilized to remove burned out products approximately every four or six hours,

which is the charging time in most plants.

Owing to the fact that the deposits are frequently burned out or removed, the de osits will be very small during each run and lience the deposits will be more readily removed when a draft through the retort is directed into the valve box in the manner stated.

The interior of the washer stand-pipe is provided with a deflector 23 at each of the ports to prevent water from running into the valve box and gaining access to the mouth piece of a retort.
